PATENT OFFICE 2 Claims.

The present invention relates tonew and useful improvements in diving devices for use particularly as a toy or as an advertising novelty in show windows,-etc., and has -for one of its important objects to provide, in a manner as hereinafter set forth, a toy or advertising novelty of this character embodying a member in the form of a-bell or the like whichis adapted to submerge and rise to the surface, together with novel means for automatically controlling rsaid member.

Another very importantfobject of the invention `is to provide a device of the aforementioned character comprising novel means for Vcausing the diving member to remain submerged for a predetermined length of time.

Still another very important object of the invention is to provide a toy or advertising novelty of the character described which is adapted to emit a jet of water when the divingmember rises to the surface thus enhancing Ythe Aattractiveness and novelty of the device.

Other objects of the invention are Vto provide a diving device of the character set forth which will be comparatively simple in construction, strong, durable, attractive in appearance, highly amusing and which may be manufactured at low cost.

All of the foregoing and still lfurther object and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in vertical section through an embodiment of the invention.

Figure 2 is a detail View in horizontal section through the diving bell, taken substantially on the line 2-2 of Fig. 1.

Figure 3 is a horizontal sectional view through the device, taken Substantially on the line 3-3 of Fig. 1.

Figure 4 is a view in vertical section through the float operated air exhaust valve.

Figure 5 is a View in vertical section through the bell operated air control valve.

Figure 6 is a View in vertical longitudinal section through the automatic pressure controlled valve.

Figure '7 is a view in vertical section through a modification.

Referring now to the drawings in detail, it will be seen that the reference numeral designates an elongated, substantially cylindrical container of glass or other suitable material for the reception of water, as at 2. Mounted vertically on the bottom 3 of the container I is an air control valve which is designated generally by the reference numeral 3. -As best seen in Fig. 5 of the drawings, the valve 4 includes an upstanding tube 5 having mounted therein and projecting thereabove a spring and pressure seated core 6. An air line 1, from a suitable source of supply, enters the lower portion of the container and is connected to the tube `5.

The reference numeral 8 designates a platform which is yieldingly mounted on the bottom 3 of the container through the medium of coil springs 9. The platform 8 has formed therein a centrally located opening I6 for the reception of 'the upper portion ofthe valve 4. Mounted on the platform 8 over the opening |Il is a cage which is engageable with the core 6 of the valve 4 for actuating said core to open position when the platform 8 is depressed.

The reference numeral I 2 designates a diving bell which is mounted for vertical movement in the 'container I, said diving bell being provided with suitable weights I3. Mounted on the substantially dome shaped top I4 of the bell I2 and communicating with said bell is a float chamber I5. As best seen in Fig, 4 of the drawings, the oat chamber I5 includes a depending neck I6 which is fixed in an opening provided therefor in the top I4 of the bell I2 and which has formed in its lower end portion a seat In the top ofthe float chamber I5 is a port I8. One or more drain openings I9 are provided in the lower portion of the float chamber I5. Mounted for operation in the chamber |5 is afloat 20. 2| depends from the float 20 and has fixed on its lower end a valve member 22 which is engageable With the seat I1.

VInterposed at any suitable point in the air line 'l is a pressure operated valve which is designated generally by the reference numeral 23. Referring to Fig. 6 0f the drawings, it will be seen that the valve 23 includes a housing 24 comprising a pair of complemental half sections secured together as at 25 and between which a diaphragm 26 is A stem :Y

able in a guide 33 which is provided therefor in the chamber 28. A coil spring 34 encircles the stem of the valve 3| and has one end engaged with the guide 33 and its other end engaged with the diaphragm 25. A by-pass 35 on the housing 24 establishes communication between the chambers 2l and 28. Interposed in the bypass 35 for controlling same is a hand operated needle valve 3B.

Brieiiy, the operation of the device is substantially as follows:

When the bell |2 submerges water enters the chamber l5 and causes the iloat 20 to rise, thus engaging the valve member 22 with the seat for closing the neck I6. When the bell l2 comes to rest on the platform 8 said platform is depressed against the tension of the supporting springs 9 and the valve 4 is opened by the engagement of the cage with the core 6. Air from the line l is thus discharged into the bell l2 and displaces the water therein. When the bell i2 has gained sufficient buoyancy in this manner, said bell rises to the surface of the water 2. Of course, when the platform 5i is thus relieved of the weight of the bell I2, said platform is raised to its former position by the springs il and the valve 4 closes. When the bell I2 reaches the surface of the water the chamber l5 empties and the float 253 drops thus opening the valve 22 and permitting the air in said bell l2 to escape. After the air escapes therefrom, the bell I2 again submerges and the foregoing operation is repeated. Through the medium of the pressure operated valve 23, the bell l2 is caused to remain submerged for a predetermined length of time. There is normally greater pressure in the chamber 2l than in the chamber 28 with the result that the diaphragm 26 closes the valve 3| against the tension of the coil spring 34. Air under pressure flows slowly around the diaphragm 2G through the valve controlled bypass 35 from the chamber 21 to the chamber 28. When the pressure in the chamber 28, with the assist-ance of the spring 34, balances the pressure in the chamber 2, the valve 3| is opened by the diaphragm 26 for permitting the air to flow from said chamber 23 to the valve 4. This operation of the valve 23 may be repeated several times beiore sufficient air passes into the bell I 2 to cause said bell to rise to the surface of the water. Of course, when the pressure in the chamber 28 drops with the discharge of the air therefrom, the diaphragm 25 again closes the valve 3|.

In the modification shown in Fig. 7 of the drawings, a neck 37 is xed in an opening which is provided therefor in the top I4 of the bell l2. Formed in the lower portion of the neck 3l is a seat B. Depending from the neck 3l into the bell i2 is a bowl 3S having an arcuate intake pipe 4i) communicating therewith. Mounted on the neck 3l is a iloat chamber 4| having a port 42 in its top. The chamber 4| is further provided, in its lower portion, with one or more drain ports 43. Interposed between the chamber 4| and the neck 3l is a diaphragm d4. A guide 45 is mounted in the neck 3l and slidable therein is the stem 46 of a valve 4l which is engageable with the seat 38. The upper end of the stem 46 is engaged with the diaphragm 44. A spring 48 yieldingly urges the valve 41 toward closed position. Mounted on the neck 31 and communicating therewith is an upstanding discharge pipe 49.

In the operation of the modification shown in Fig. '7, when the bell |2 submerges, the bowl 39 and its upwardly curved intake pipe 40 fill with water and a float 5|) in the chamber 4| rises as said chamber also fills, thus relieving the diaphragm 44 of the weight of said float and permitting the valve 41 to close. When the bell |2 again rises to the surface, the chamber 4| drains or empties and the float 50 drops and comes to rest on the diaphragm 44, the weight of said iloat being sufiicient to depress said diaphragm and open the valve 4l. When the valve 4'! is thus opened the water which has been trapped in the bowl 39 and the intake pipe 40 thereof is ejected by the escaping air in the bell l2 through the pipe 49.

It is believed that the many advantages of a diving device constructed in accordance with the present invention will be readily understood and although preferred embodiments of said device are as illustrated and described, it is to be understood that further modifications may be resorted to which will fall within the scope of the invention as claimed.
